An optimal algorithm for the robotic assembly system design problem: An industrial case study

2020 , Hagemann, S. , Stark, R.

The design process of flow-oriented assembly systems is characterized by being both highly complex and time consuming. Especially those design processes categorized into robotic and multi variant encountered in the automotive body-in-white production stages. Unlike established manual and template-based assembly system design models, which are currently applied in industry, the here presented novel approach uses a knowledge-based search algorithm and automatically generates optimal assembly system configurations. The algorithm has been implemented in a software prototype and the results have been validated against different large-size industrial scenarios in the automotive field of body-in-white production.

Modellbasierte Prozess- und Systemgestaltung für die Innovationsbeschleunigung

2011 , Damerau, T. , Kaufmann, U. , Knothe, T. , Stark, R. , Ulbrich, A.

Modelbased Process and Systems Modelling to accelerate innovation management - Joint research project ISYPROM. The main objective of the ISYPROM project was the tighter integration between virtual product creation and enterprise/ business process modelling to support a holistic view and optimization of product development and innovation processes. In support of this objective the project focused on the implementation of more formalised, model-based and therefore computer interpretable representations of products and their corresponding product development processes with the overlaying enterprise and business processes.

Development capabilities for smart products

2019 , Tomiyama, T. , Lutters, E. , Stark, R. , Abramovici, M.

Smart products supported by new step-changing technologies, such as Internet of Things and artificial intelligence, are now emerging in the market. Smart products are cyber physical systems with services through Internet connection. For example, smart vehicles equipped with advanced embedded intelligence are connected to other vehicles, people, and environment, and offer innovative data-driven services. Since smart products are software-intensive, data-driven, and service-conscious, their development clearly needs new capabilities underpinned by advanced tools, methods, and models. This paper reviews the status and trends of these emerging development technologies such as model-based systems engineering and digital twin.

Nachhaltige Produktentwicklung: Eine interdisziplinäre Herausforderung

2011 , Woll, R. , Hayka, H. , Lindow, K. , Stark, R.

Eine nachhaltige Produktentwicklung muss darauf abzielen, ein Produkt zu entwickeln, welches über seinem gesamten Lebenszyklus hinweg Nachhaltigkeitsforderungen erfüllt. Da ein Produktentwickler alleine diesen nicht ausreichend überblicken kann, muss die Konzeption und Gestaltung eines Produkts in interdisziplinärer Zusammenarbeit mit Experten aus anderen Fachgebieten durchgeführt werden. In dem Projekt "Methodische Nachhaltigkeitsbewertung von Maschinenkomponenten im Entwicklungsprozess" wurde eine Methodik entwickelt, bei der Produktentwickler, Prozess- und Nachhaltigkeitsexperten gemeinsam dazu beitragen, Gestaltungsalternativen für ein Produkt bezüglich ihrer Nachhaltigkeit bewertbar zu machen.

Competing in engineering design - the role of virtual product creation

2010 , Stark, R. , Krause, F.-L. , Kind, C. , Rothenburg, U. , Müller, P. , Hayka, H. , Stöckert, H.

Product creation is facing the next level of fundamental changes. Global demands are growing substantially to achieve energy efficient and sustainable value creation networks for production, products and services without compromising traditional success factors such as time to market, cost and quality. To stay competitive within such an environment development partners in industry and public sectors will require new interplay solutions for engineering design execution, domain knowledge representation, expert competence utilization and digital assistance systems. This scenario offers the chance for virtual production creation solutions to become critical for the future by offering unique engineering capabilities, which have not yet been explored or deployed. The paper investigates key elements of modern Virtual Product Creation - such as agile process execution, functional product modeling and context appropriate information management - towards their competitive role in satisfying increasing numbers of product requirements, in delivering robust systems integration and in ensuring true sustainable product lifecycle solutions.

Computertomographie für die Instandhaltung von elektronischen Baugruppen

2012 , Grosser, H. , Politz, F. , Beckmann-Dobrev, B. , Müller, P. , Stark, R.

Elektronikkomponenten werden im Luft- und Schienenverkehr oft durch die Anwender selbst oder durch speziell qualifizierte MRO-Dienstleister (Maintenance, Repair and Overhaul) instand gehalten. In der Regel stehen jedoch nicht alle Unterlagen der Hersteller zur Verfügung, sodass die Fehlersuche für Reparaturaufgaben sehr aufwendig wird. Das Fraunhofer IPK hat eine Prozesskette zur schnellen Generierung von Stromlaufplänen, Bestückungsplänen und Stücklisten entwickelt und ausgewählte Prozessschritte prototypisch umgesetzt.
